RAILROAD-CAR-WINDOW CONSTRUCTION.

Application led September 6, 1928. Serial No. 304,248.

Our invention relates to railroad car win- Y dow construction, and is analogous to the invention set forth in our pending application, Serial No. 260,946, but is a further development of the latter so far as double and single window constructions and the sash holding means are concerned.

One object of the present invention is to so construct and equip the center stops that they will carry the felt channels within which the side edges of the window panes track, will be resiliently backed so that said channels will closely hug said edges, and will be secured as Iagainst lengthwise movement without interfering with the resilient action of the stops.

Another object is to provide an engagement at all times betweenl the sash holding members and the racks with which said members cooperate, thus rendering the sash holding means, as a whole, immune from the disadvantages resulting from the weaving and twisting of a car sothat the distance between the racks and the sash holding member will always remain constant.

A still further object is to provide weather proof packing between the sides of the center stop and the inside and outside stops and between the latter stops and the window casing.

Also, this invention aims to do away with the practice of locating the casing for the sash holding mechanism on the inside face of the inner sash, and also to remove the said sash, thus improving the general appearance of the sash and its surroundings. The general requirements noted in said pending application with respect to car window constructions, characterize the present structure, and it will therefore be under-v stood without needless repetition, that such requirements obtain in the invention described and claimed herein.

Referring to the accompanying drawings which illustrate a preferred embodiment of our invention Figure l is a broken elevation, partl in section, of the lower left hand corner o the outside sash of a double window construction, the parts in section being cut at the line 1 1 of Figure 4.

cooperating side racks from the inside of Figure 2 is a broken elevation, partly in section, and showing the lower right hand portion of the double sash construction.

Figure 3 is a section at the line 3-3 of Figure 2.

Figure 4 is a section at .the line 4-4 of Figure 3. t

Figure 5 is a section at the line 5-5 of Figure 2.

Figure 6 is a detail b-roken sectional elevation of one side of a window as it appears with the center stop and racks in position, and with all parts of the sash removed.

Figure `7 is a section at the line 7-7 of Figure 6.

Figure 8 is an elevation of the right hand corner of our invention adapted for a single sash construction.

Figure 9 is a section at the line 9-9 of Figure 8.

Figure 10 is a section at the line 10-10 of Figure 8.

Figure 11 is a detail sectional elevation of the form of sash holder mechanism shown at Figure 8, and

Figures l2, 13, and 14, are respectively sections at the lines 12-12, 13-13, and 14-14, of Figure 8.

Similar numerals of reference denote like parts in the several figures ofthe drawing.

Our invention is applicable to both the single and the double window' constructions, so far as sash holding means' isconcerned, but, since the major portion of the illustrations herein, as well as all the features of the invention are to be found in the double window constuction, we will first describe this latter construction, referring particularly to Figures l to 7 inclusive.

-No'reference will be made herein to the bottom sill construction and the parts carried by the bottom rail of the sashes that cooperate therewith, since in these respects the invention herein illustratedv is the same as that shown and described in our pending application aforesaid.

l, 2, are the glass panes for the inside and outside sashes respectively, and 3, 4, are respectively the bottom rails of these sashes.

5 is the inside stop of the window construction and 6 the outside stop.

Between these stops is located the center JERSEY, A CORPORATION OF T stop 7 which is preferably formed with a rib-like part 8 extending throughout the length of its middle portion, ilat faces 9 on each side of this rib and. at right angles thereto, while ledges l() parallel with the faces 9, constitute the lateral terminals of the center stop. l

Of course, it will be understood that the inside and outside stops as well as the center stop and all parts in connection therewith,

are applied on opposite sides of the window opening, lbut we have illustrated and' will describe only one side of the'window opening so far as equipment in these respects 1s concerned, since both sides are duplicates one of the other. y

vIt will therefore be understood that this center stop 7 has a step-like formation, and to the inside of this stop at its lower end is secured a block 11by means of rivets a, and threaded through the rib 8 and this block is a pin 12 whose free extremity extends loosely through the side window post 13, as shown at Figures 3 and 7 Secured to the center sto by means of rivets b is a plate 14, and i) om this plate are lanced lugs 15 with which the upper coil of a` spring 16 is connected, the free end of the spring bearing against the window post.

The construction just described is shown particularly at Figures 5 and 7, and it will be noted that there are 4several of these springs throughout the length of the center stop, all of which are secured in the manner just described. Securd'to the faces 9 of the center stop by means of rivets e are racks 17 which are engaged by thesash holding devicesin the manner presently to be explained. 1 n 18, 19, are trough-like metal containers which seat respectively against the ledges 10 and housed within these containers are the felt channels 20 and 21, within which channels the side edges of the glass panes 1 and 2 track. i

The function of the coil springs 16 is to force the center stop toward the center of the window opening so as to cause the side edges of the glass pane to always be in close con-` tact with the felt channels, and if there is any variation in the size of the window opening-or size or width of the window pane, these springs will yield to compensate for such variations.

The function of the pin 12 is to prevent the upward movement of the center stop when the window sashes are raised, and at j the same time to permit of the free resilient movements of the center stop owing to the free play which the pin has through the side window post.

A weather stripping 22 is secured to one edge of the metal container 18 and is conned by the insidestop 5 against the side of said container, the strip being likewise firmly bottom rails hand-holds for conveniently raising the windows and means for cooperating with the racks 17 for either locking the sashes in their lowered positions or for holding such sashes at desired elevations, and descriptions with reference to these matters will now be given.

24, 25, are hand-lifts secured respectively to the inner faces of the bottom rails of the inside and outside sashes. To thev outer face of the rail 3 is secured the casing 26 which contains the mechanism for throwing the dog 27 into engagement with the opposite rack 17, and 28 isthe operating lever which is in the form of a crank that is secured to any suitable means for operating said mechanism `to withdraw saidy dog from the rack.

The casing 29 for the mechanism that throws the dog 30 into engagement with its opposite r-ack 17 is secured to the inner face of the rail 4.-, and in this instance the lift 25 and this casing'are preferably cast integrally. Theconstruction of this lift and casing as well as the mechanism in the latter and its relation to the lever 31 operable to withdraw the dog 30 from the rack being the same as will hereinafter be described with reference to Figures 11, 12, and 13. But at this point we would say that this invention 'is not limited to the use of any particular means for effecting the engagement of the dog with the racks or for withdrawing said dogs from these racks, since we merely have employed suitable means to demonstrate that the sash holding instrumentalities are en gageable for reasons heretofore noted.

In the -instance of both sashes,`the operating levers 28 and 31 terminate in thumb rests 32 and 33 which overhang the hand lifts and are juxtaposed for convenience in withdrawing the d ogs and raising the sashes.

In the arrangement above described it will bcnoted that no part of the sash holding means is on the inside of the inner sash,

with the exception of the lever 28, and thisl enhances the general appearanceof the win- ,dow structure when viewed from the inside of a car. j

The ribs 8 are provided sincethey present convenient means for mounting screens whose side stiles are grooved, but this rib may be. omitted and the faces 9 merged into a single face, in which instance both racks could be formed on one strip extending the full width of the face, the sides of which rack would, ofcourse, be the only portions enga-geable by the dogs; or, two racks sccured as shown could be employed.

The construction Ashown at Figures 8 to 14 inclusive, which illustrates our invention as applied to a single sash, does not materially differ from that of either the inner or outer sash of the double window construction with the exception that the center stop necessarily varies somewhat in its construction. The inner and outer stops, the glass pane 1 and bottom rail 3, the post 13,the metal container 19, with its felt channel 20, and weather strip 23, are all precisely the same'in structure` and operation as the similar parts heretofore described with respect to the inside sash, and the casing for the sash holding mechanism and hand lift are the same as those illustrated with respect to the outside sash, that is to say, they are secured to the inner face of such sash, so that the dog will engage the rack in the manner presently to be described.

34 is a generally U-shaped member having one long le 35 and one short leg 36, the long leg'bemg positioned in the rear of the metal container 19 and in direct contact therewith while the short leg abuts against one wall vof the container 19 and to the outside face of the short leg is secured the rack 17 by means of rivets 37 (only one shown). v

38 is a block that is secured tothe short leg 36. by means of headed pins 39 and this block extends through an elongated gate 40 cut within the inner face of the inside stop 5 so that it will be clear that the entire structure comprising the U-shaped member 34 and block 38, the rack 17 and the metal container 19 with its felt channels 20, will all be capable of a movement in harmony lengthwise of the gate 40.

Secured to the rear face of the long leg 35, my means of rivets d, are springs 4l (only one shown) so that it will be evident that the movements of the parts previously described will be resilient, and it will therefore be clear that the dog 30 of the sash holder device will bein contact with the resilient acting rack, so that the advantages of this peculiarity will be precisely the same as those noted above wit-h respect to the structure hereinbefore described.

The center stop that is composed of the U-shaped member 34 andthe parts in contact therewith and carried thereby, is embraced on opposite sides between -the inside `stop 5 and the outside stop 6, so that the window construction in these respects does not at all diifer from that heretofore noted.

The object of the block 38 which is confined between the walls of the elongated gate 40 is to prevent upward movement of the center stop when the sash is raised, as will be clear by reference to Figure 8, and in respect to this block as Well as the pin 12 vinside andoutside stops heretofore mentioned i`n connection with the double window construction, any ordinary means for effecting the result accom lished by these elements may be employe since they merely serve to prevent upward movement of the center stop, while at the same time they permit the resilient movements of the latter.

lVith reference to the sash holding means employed, where the casing and hand lift are secured on the same side of the window sash, the construction shown at Figures 11, l2, and 13, illustrate this fully, and, referrino to these figures, the dog 30 is pivoted within the casing and has a tail 42 that is engaged by a finger 43 at the innerpend of the operating lever 31, the latter being fast on a pin 44 whose ends bear loosely Within opposite sides of the casing, a coil spring 45 being interposed between the dog and the heel of the operating lever, the function of this spring being to normally throw the dog outwardly, while the depression of the operating lever 31 will act to withdraw the dog against the resiliency of this spring.

This is a very ordinary construction, and while it serves the purposes of our invention, nevertheless we do not wish to be limited to the use ofany particular sash holding mechanism so long as such mechanism engages with racks that are carried by a resilient center stop. Y D

Wliile it is not deemed at all necessary to refer in detail to the manner in which the lever 28 is connected with the mechanism in the casing 26, in connection with the inside sash of the double window construction, we will say that this lever 28 is a separate element and is secured to the pin 44 in any suitable way, after the manner of an ordinary crank, so that it will be clear that in the constructions shown at Figure 2 and at Figure l1, the depression of the levers 28 and 31 whereby 'said racks are constantly maintained in a fixed relation to the sash holders, and means for preventing lengthwise movement of the guideways Without interfering l with the resiliency of the latter.

2. A double window construction, comprising center stops that carry metal pockets, channels of suitable material confined within said pockets, window panes whose side edges track within said channels, resilient means interposed between said stops and the sides of the windowcasing, and that bear. againstsaid pockets. v

. 3. A construction as in claim 2, in which side racks are carried by the center stops and cooperate with sash holding devices carried by the window sashes.

4. A construction as in claim 2, in which \pins are secured to the center stops and extend loosely at their free ends through the Window posts.

5. A construction as in claim 2, with the addition that weather paokingsare secured to said pockets and extend between the pockets and the inside and outside stops and are confined between said stops and the window casing. f

6. In a railroad car wlndow construction comprising resilient center stops that carry I'tures hereto.

the channels within which the side edges of the window panes track, sash holder mechanisms that are contained within casings which are secured respectively to the outside face of the bottom rail of the inner sash and to the inside face of the bottom rail of the outside sash, racks carried by said stops and capable of being engaged by said mechanisms, hand lifts'carried by the inside faces of said rails, and operating'levers connected with said mechanisms and extending in close proximity to said lifts.

In testimony whereof we aflix our signa- JOHN L. MoHUN. HENRY Pinson.
